Sir, mastec mas830l ka original led display board or motherboard market pe milte hai alagse ?
I think no.
Plz full name of sensor n availability?
Magnetic float switch.
15-20 se jyada chalta n h
Batery backup jyada n h iska
nice
great...
Sir how to caliberate mastech it shows resistance 0.7 ohm on it
.7 Ohm reading in 200-Ohm range is normal
good sair
ये कैसे पता होगा की फुल चार्ज हो गई है
There is no indication, Recharge the torch for 30 to 45 minutes..
i don't see a depth stop on this
Who developed this project first broh
I might have done it 🤔
Can i use potentiometer meter 10k instead of Variable resistor 5k
Yes.
Sir but it is not working based upon temperature, causally when we connect the power supply, the fan automatically starts rotation and also the bulb glowing.
@@vishalgowtham6351This is a comparator circuit using an operational amplifier Check the voltage on I.C pin-Three. Then set the voltage of I.C pin-Two .02 voltage more than pin number three. Example: if voltage ofpin-3 is 5.V, Then set pin 2 voltage to 5.02V ( use the potentiometer for adjusting)

Aapka video lajawab hua hai per Mera ismein DC rechargeable system Kiya hai voltage adjust karke Diya fir bhi wrong voltage show kar raha hai kya problem ho sakta hai
My multimeter is doing same thing.. and it is the same model
Hey,can you give the components required list and it's range and quantity.plz
components list and circuit diagram are given in the description..😊. ( This is a simple transistor based hobby circuit for learning.. 5...10cm is the range)
What is the yellow thing used?
Connecting wires
it isnt working, i triple checked everything, can i have some tips?
Sorry about my late reply. I have checked the circuit schematic i couldn't find any mistake on it. How did you test the circuit ? On breadboard or soldering? You used the same components as I have shown in the circuit?
i checked everything and it looks clear to me, just incase i missed smth about my basics. Does the type of transistter matter I used a mosfet and some transistters
@@synctax1017 yes the transistor are very critical. You should use the same transistors for working the circuit.
@@etechniques I never knew, Thanks for your patience and your useful information. Enjoy your day!
@@synctax1017 thank you.. 😊.
As soon as I connect the battery Led lights up and buzzer beeps not when i spark a fire I have used Ir photodiode but still can you help
1.Please check the polarity of the photo diode. ( Anode to base and cathode to positive) (If not solved do the 2nd step) 2. Remove the photo diode and connect to the power supply. If the buzzer beeps without the photo diode, the problem may be with the transistor or wiring issue.
I have checked the polarity its correct and after removing the photodiode the buzzer doesn't beep. So what can be the issue still I am having same provlem

Please mention the legend mark of burned resistor
Nice bhai
Magic, got it
Can you please please please tell the type of transistor used and the capacitor used and the values of resistors used and the power supply (basically provide with a circuit diagram)

Which variation of photo diode you used?
Any 3mm or 5mm photo diode
sir woh do jumper wires kaha lagaye aapne ?? plzz tell
You mean on the top side? Those two jumper wires on top are connected to Supply positive. And the other two jumpers (one short and one long) are connected to Supply Negative. Thanks for watching my videos😊👍👍
sir i am talking about that one red one and the other black one@@etechniques
@@itskrishna_live Red and black wires are Supply positive and Negative wires
sir 100 ohm ke jaga 67 ohm ka chalega ??
@@itskrishna_live yes you can use
Please give me contact number
I want to create a major project for my final year can you help?

Is it works in light???
If the light contains more infrared, otherwise not. 🌞🌞🌞This circuit senses sunlight

Good job
hello sir please send wiring diagram
Circuit diagram link already in the description. Please check 👍
Heyyy, if i remove the buzzer keeping everything else same, will a 9v power supply work? urgent
It works. But may the sensitivity decrease

Yes u can use 4007
Can i use 9v dc battery for power supply
Plzz reply soon
Yes

I have same multimeter same model lam facing problem like above countineous beep sound on continty mode without to sorting the probes. Other parameter also not proper no physical damage on component side l checked sliders are OK plguide me thanks
Did you check the two fuse
Bhai please isko thoda Modify krke ek lithium battery lagao jo jada bacup deti ho 1or 2 hrs please
